Explain your code
There are already lots of preloader tuts out there, I guess you didn't look hard enough. You also really need to explain the code, not say go and look somewhere else. At least provide a link!
Colour scheme was horrible, and the layout was bad. Okay you wanted it to be small and simple, but you can have decent colours, or even keep it black and white.
It's great, honestly, that you're helping others. But individual tuts are best in collaborations, things that people don't really know of, and not in Flash.
